    The present study was conducted to investigate the performance of Badarpur fly ash stabilized with lime and gypsum. The work investigates the effect of lime (4%, 8%, 12% and 16% by mass of dry fly ash) and gypsum (1%) on compaction (in terms of density/moisture relationship), unconfined compressive strength (UCS), California bearing ratio (CBR), split tensile strength, and resilient modulus of fly ash. Based on strength, fly ash stabilized using 12% lime and 1% gypsum was observed as the highest strength mix. The microstructural development of the stabilized mix was studied through SEM and XRD. The results showed that Badarpur fly ash acquired UCS of 4697 kPa, CBR of 73% after 28 days of curing, split tensile strength of 630 kPa, and resilient modulus of 651 kPa. The strength increases with curing period and the composite achieved strength of 6150 kPa after 90 days of curing. This stabilized Badarpur fly ash can be utilized as road construction material

    A bacterial strain Bz02 was isolated from a water sample collected from river Gomti at the Indian city of Lucknow. We characterized the strain using 16S rRNA sequence. Phylogenetic analysis showed that the strain formed a monophyletic clade with members of the genus Comamonas. The closest phylogenetic relative was Comamonas testosteroni with 95% 16S rRNA gene sequence similarity. It is proposed that the identified strain Bz02 be assigned as the type strain of a species of the genus Comamonas (Comamonas sp Bz02) based on 16S rRNA gene sequence search in Ribosomal Database Project, small subunit rRNA and large subunit rRNA databases together with the phylogenetic tree analysis. The sequence is deposted in GenBank with the accession number FJ211417

    WHO-defined pneumonias, treated with antibiotics, are responsible for a significant proportion of childhood morbidity and mortality in the developing countries. Since substantial proportion pneumonias have a viral etiology, where children are more likely to present with wheeze, there is a concern that currently antibiotics are being over-prescribed for it. Hence the current trial was conducted with the objective to show the therapeutic equivalence of two treatments (placebo and amoxycillin) for children presenting with non-severe pneumonia with wheeze, who have persistent fast breathing after nebulisation with salbutamol, and have normal chest radiograph.This multi-centric, randomised placebo controlled double blind clinical trial intended to investigate equivalent efficacy of placebo and amoxicillin and was conducted in ambulatory care settings in eight government hospitals in India. Participants were children aged 2-59 months of age, who received either oral amoxycillin (31-54 mg/Kg/day, in three divided doses for three days) or placebo, and standard bronchodilator therapy. Primary outcome was clinical failure on or before day- 4.We randomized 836 cases in placebo and 835 in amoxycillin group. Clinical failures occurred in 201 (24.0%) on placebo and 166 (19.9%) on amoxycillin (risk difference 4.2% in favour of antibiotic, 95% CI: 0.2 to 8.1). Adherence for both placebo and amoxycillin was >96% and 98.9% subjects were followed up on day- 4. Clinical failure was associated with (i) placebo treatment (adjusted OR = 1.28, 95% CI: 1.01 to1.62), (ii) excess respiratory rate of >10 breaths per minute (adjusted OR = 1.51, 95% CI: 1.19, 1.92), (iii) vomiting at enrolment (adjusted OR = 1.49, 95% CI: 1.13, 1.96), (iv) history of use of broncho-dilators (adjusted OR = 1.71, 95% CI: 1.30, 2.24) and (v) non-adherence (adjusted OR = 8.06, 95% CI: 4.36, 14.92).Treating children with non-severe pneumonia and wheeze with a placebo is not equivalent to treatment with oral amoxycillin.ClinicalTrials.gov NCT00407394

    Context: Keloids and hypertrophic scars are a cause of severe impairment of quality of life. Intralesional triamcinolone acetonide has been used at different intervals at various centers. Aim: This study was aimed to compare the efficacy of intralesional triamcinolone acetonide at 2-, 4-, and 6-week intervals in hypertrophic scars and keloids. Settings and Design: This study was conducted in the plastic surgery outpatient department of a tertiary care hospital. This is an interventional prospective study, randomization was done using a computer-generated sequence. Materials and Methods: In this study conducted from October 2015 to January 2017, administration of triamcinolone acetonide 40 mg/ml at 2-weekly, 4-weekly, and 6-weekly intervals was done in case of hypertrophic scars and keloids for up to 8 doses or till Vancouver Scar (VCS) scale of 4 was achieved. VCS, pain, and itching were noted and compared. Statistical Analysis: VCS scale was used for comparison using analysis of variance test. The visual analog scale was compared using an unpaired t-test. Qualitative data were compared using the Chi-square test/Fischer's exact test. P < 0.05 was considered statistically significant. Results: The 2-weekly regimen was found to show better results in terms of pain and scar improvement. It also required a lesser number of doses to produce the same effect. The response to itching was comparable in 2- and 4-weekly groups and was better than 6-weekly group. Minimal complications were noted in the three groups. Conclusion: Two-weekly regimen of triamcinolone acetonide is recommended for intralesional use in hypertrophic scars and keloids

    Giant Myofibroblastoma of the Male Breast: A Case Report and Literature Review

    No full text
    Myofibroblastomas are soft-tissue neoplasms that are thought to arise from myofibroblasts. They are mostly observed in males 41–85 years of age; however, this lesion also occurs in women. The usual clinical presentation is a unilateral painless lump that is not adherent to overlying or underlying structures. Microscopically, myofibroblastomas can be divided into 5 subtypes: classical, epithelioid, collagenised, cellular, and infiltrative. Mammary ducts and lobules are absent in the typical histological subtypes and the adjacent breast parenchyma may form a pseudocapsule. The majority of myofibroblastomas are immunoreactive for CD34, desmin, smooth muscle actin, and vimentin and are negative for cytokeratin and S-100 protein. We present a case of a giant myofibroblastoma arising in the background of gynecomastia in an adult male

    In situ gel formulations have been widely reported as a carrier for sustained release delivery systems due to certain advantages such as targeted drug delivery, minimal invasiveness and potent therapeutic activity. Herein, in situ gel system for sustained release of doxorubicin and ibuprofen for anti-cancer and anti-inflammatory activity is reported. Doxorubicin-conjugated alginate (dox-alg) gel was prepared using EDC-NHS chemistry and loaded with ibuprofen encapsulated polycaprolactone (PCL) microparticles (dox-alg composite). PCL microparticles were prepared by a solvent evaporation method (size 50 - 100µm). The gel was characterized using SEM, FTIR, XRD and TGA analysis. Dox-alg composite gel showed good syringeability and gel formation properties. Burst release was observed for both drugs within 24 h followed by sustained release till day 21. Doxorubicin released from composite showed considerable cytotoxic effect. Cell uptake was confirmed by confocal microscopy using MDA-MB-231 cells. Anti-inflammatory activity of ibuprofen released from composite gel was compared with the free drug. An injection of dox-alg composite gel in the tissue would fill the void created after tumor removal surgery, prevent the resuscitation of remnant cancerous cells and reduce inflammation. Thus, the dox-alg composite gel could be a potential agent for the dual anti-cancer and anti-inflammatory therapy

    Background : The objective of the paper is to review the incidence and types of associated urogenital anomalies (U.G.A.) we encountered in patients with anorectal malformations (A.R.M.) and compare the results with previously published world literature. Materials and Methods: Retrospective review was done of 220 cases of A.R.M., treated from May 2002 to April 2003. All patients routinely underwent ultrasound (U.S.) study of the K.U.B. region and pelvis and lumbosacral radiography. Voiding cystourethrography (V.C.U.G.), nuclear renography and other investigations like buccal smear and karyotyping were done in selected cases only. Results: Genital anomalies were found in 30 cases (13.63%) and urologic anomalies in 25 cases (11.36%), a direct correlation being found between the level of A.R.M. and the incidence of urogenital anomalies (U.G.A.). Conclusion: The high incidence of associated anomalies (24.54%) makes careful clinical examination and evaluation of the urinary tract during the neonatal or early infantile period mandatory in all cases of A.R.M., particularly to avoid deterioration of renal function in future
